Abstract
The utility model provides a structure of upright wheel filter system, characterized in that a distributing wheel and a stable wheel are fixed after being rotated anti-clockwise for 25 degrees, lower two adsorption areas of the distributing wheel are not provided with area adjusting plate, the top of a material hopper and a scraper are horizontally arranged. The utility model has simple realization, without much modification on former upright wheel filter, with low modification cost, which can reduce the liquid content of filter cake in the upright wheel filter and be used to upgrade the upright wheel filters of alumina industry and device industry.
Description
Technical field
The utility model relates to the Separation of Solid and Liquid field, especially relates to a kind of improvement that the aluminum oxide production process kind is divided the vertical-disk filter system architecture configuration of filtering usefulness that is used for.
Background technology
France's Bi Sinie company (method aluminium) one-stage process is produced the sandy alumina decomposition technique, has that flow process is simple, technology reliable and advantage such as constant product quality, by many alumina producing producer is adopted.This technology has been adopted in the decomposition of our factory alumina producing seed just, its concrete technology is, the seminal fluid that the sedimentation operation is produced with enter decomposer after crystal seed mixes and decompose, slurries after the decomposition enter cyclone classification, underflow is as product, overflow is sent into vertical-disk filter and is filtered, and filter cake is as crystal seed, and filtrate is carried out evaporation and concentration.
What the our factory seed filtered employing is the homemade 114m2 vertical-disk filter of method, its collects suction separation, drying and is discharged to all over the body, its primary structure is divided into cell body, hollow spindle, main drive, fanning strip, dispensing head, doctor blade device, blower system, pumped vacuum systems and discharging device etc., and wherein the dispensing head structure mainly is divided into distribution plate, quiet dish and Moving plate.3 filtering tables of axially-aligned on the hollow spindle, each filter disc has 48 fan-shaped filters, and per two fan-shaped filter correspondences a passage on the hollow main shaft, under the cooperation of distribution plate and quiet dish, each passage be the imbibition passage be again blowback wind passage, filter disc is with filter cloth; Whole filtering table is divided into material sucking area, dry section and discharge zone, and material sucking area forms the graininess filter cake by the formed pressure differential of vavuum pump on filter cloth, and discharges liquid phase by filter cake and filter cloth, reaches the purpose of liquid-solid separation; Filter cake is sloughed wherein most of attached liquid at dry section, and filter cake enters discharge zone, the compressed air that provides by the air compressor machine part filter cake that blows off, and remaining finishes a circulation by scraper discharging.
One-stage process is produced the sandy alumina decomposition technique and is had slurries degree of supersaturation height, the high characteristics of seed ratio, so the crystal seed internal circulating load is big, the size of crystal seed filter cake attached liquid rate is bigger to the influence of mother liquor amount later that it carries.
At present, the filter cake liquid holdup of new and effective upright dish vacuum filter all reaches below 16% both at home and abroad.And the our factory seed filters the filter cake liquid holdup of the used upright dish vacuum filter of operation more than 20%, the mother liquor amount that its filter cake is carried under one's arms is big, can cause the decomposing system liquid measure to increase on the one hand, and energy consumption strengthens, reduce decomposition slurries RP value on the other hand, be unfavorable for improving product strength and seminal fluid output capacity.
Through production practices and analysis, find filter distribution plate and drainage system unreasonable structure, when the filtrate in the filtration cakes torrefaction district was not exclusively discharged, blowback wind blew back filter cake with it, caused filter cake liquid holdup height.In addition, contain certain water in the compressed air by the generation of liquid-ring type air compressor machine, the filter cake liquid holdup is risen.
Summary of the invention
The purpose of this utility model provides a kind of structure optimization configuration of vertical-disk filter, is keeping can effectively reducing the liquid holdup of filter cake under the constant condition of production capacity.
Technical solution adopted in the utility model:
By reducing the blowback wind position of upright dish vacuum filter, increase dry vacuum area area, prolong the filtration cakes torrefaction time; Transform drainage system simultaneously, make complete, the eliminating in time of filtrate, improve drying, take off liquid efficient; Increase the drainage arrangement of liquid-ring type air compressor machine, the water content of minimizing and constant compression blowback wind.
Architectural feature is: with the distribution plate of vertical-disk filter and quiet dish be rotated counterclockwise 25 ° fixing; Two material sucking areas in distribution plate bottom are not established area regulating plate; Hopper top and blade design are that horizontal level is installed.
The beneficial effects of the utility model:
Implementing does not simply need original vertical-disk filter is done big change, and improvement expenses is cheap, can better reduce vertical-disk filter filter cake liquid holdup.Also can be applicable to the manufacturing and designing of vertical-disk filter of the vertical-disk filter upgrading of other alumina producing producer same model and device fabrication producer.

The specific embodiment
Referring to Fig. 1-4, on liquid-ring type air compressor machine 3 outlet gas-liquid separation of air jars, a cover self-draining arrangement 4 (applying for a patent in addition) is installed, improve the gas-water separation efficient of air tank, guarantee to compress blowback wind and be not with water, upright dish filter cake liquid holdup is reduced or be stabilized in below 20%.The distribution plate 5 and the quiet dish 12 of vertical-disk filter 1 (are stood and coil the card rotation direction) 25 ° of rotations counterclockwise, then can make filtering table card blowback wind zone position reduce by 25 °, be immersed in simultaneously that part card dry section breaks away from slip fully in the slip, enlarge dry section 17 areas.Dry vacuum system is thoroughly separated with the suction vacuum system, reduce the amount of filtrate that enters dry vacuum filtrate pipe 8, thereby upright dish filter cake liquid holdup is reduced to below 18%; For cooperating the change of blowback wind position, must change hopper 11 tops and scraper 10 positions of vertical-disk filter into horizontal level by existing position; Constant for guaranteeing the material sucking area area when the minimum slurry level, the two material sucking area area regulating plates in distribution plate bottom can be extracted out and not establish, constant to guarantee the upright dish production capacity when the minimum slurry level.
